The Lowdown
G’day, Rusty here. Let’s cut to it – this 16-day stretch for Tarnos is a grind. There’s a big quiet spell at the start, and even when the swell finally shows up in the last week of July, it’s messy. You’ll need to pick your moments carefully.
The first real chance comes Wednesday, July 22, with a morning glass-off and a tiny 3ft NW swell. The conditions are clean, but the energy is weak (63). For a beginner-friendly break like Tarnos - La Digue (a beach/jetty), that’s about as small as it gets. Water temp is average for this time of year, nothing to write home about.
Things stay flat and ordinary through the end of July. The next real bump hits Tuesday, July 28, with a 4ft NW swell and light cross-onshore winds. The energy is moderate (220), but the period is short (9 seconds), so the waves will be a bit weak and sectiony. It’s a marginal day, not a standout.
The biggest swell of the forecast rolls in Wednesday, July 29, with a 7ft NW swell in the morning. The energy jumps to strong (748), but the period is a short 8 seconds, and the wind is onshore. Expect big, lumpy, messy surf. For a beach break, that’s not a wave for the faint of heart – really only for the experienced crew, and even then, it’s rough.
If you’re determined, the morning of July 30 offers a 6ft NW swell with a longer 11-second period, and light cross-shore winds. The energy is still strong (717), and the longer period brings a bit more shape. It’s the cleanest of the bigger days, but the wind is cross, not offshore.
After that, the swell fades fast. By August 2, we’re back to 2ft and clean, but tiny. That’s your best bet for a quiet, small-wave session for the beginners.
The standout here is the morning of July 30 at Tarnos - La Digue. The swell is solid (6ft from NW), the period is decent (11 seconds), and the light cross-shore wind keeps it rideable. The crowd is sometimes a thing, but on a weekday in mixed-up forecast, you’ll have space. Not a classic, but the best of this run.
Signing off, Rusty.
